FILLING-VALVE.

SPECIFICATION forming part of Letters Patent No. 768,965, dated August 30, 1904.

{,Nomodel.)

To @ZZ wiz/0m 'lit may concern:

Be it known that I, FRANK C. H. STRASBUR- GER, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling-Valves, of which the following is a specification.

This invention relates to filling-valve mechanism for bottle-filling machines, and the application is a division of my application, Serial No. 164,815, tiled July 9, 1903.

The object of this invention is to avoid the production of foam in the bottle being lled by eqnalizing the pressure in the supplytank and bottle before the beer or other carbonated liquid begins to flow into the bottle, and thus causing the liquid to flow by gravity.

In the accompanying drawings, which illustrate one manner of embodying' the invention, Figure l is a sectional view showing' the filling mechanism and a portion of the supply-tank. Fig. 2 is a sectional view on the line 2. 2 of Fig. l.

Referring to the drawings, 5 designates the body of the valve mechanism, which is screwed or otherwise suitably secured to the bottom 6 of the supply-tank 7 and is provided with a bore 8, forming a liquid-passage, into the lower end of which the iilling-tube 9 is secured. by the rods Il and seats upon the rubber gasket l2 on the body around the liquid-passage therein. These rods also carry the head I3, which is provided on its outer face with a seat 1A to receive the mouth of the bottle, which is forced against said seat with suiiicient pressure to overcome the tension of the springs l5 on the rods to unseat the liquidvalve. The head is provided with an enlarged bore 1G, which receives the filling-tube and communicates with an air-chamber 17, inclosed by a rubber gasket 18, seated in the upper face of the head and the lower Jface of the body. An air-passage 19 in the body 5 communicates atits lower end with the chamber I7 and at its upper end with a valvechamber 20, which contains a spring-pressed The liquid-valve 10 is carriedair-valve 2l. This valve-chamber may be formed in any suitable manner, and a pipe 22 is connected therewith and extends up in the tank above the level of the liquid therein. A valve-stem 23, which may or may not be connected to the valve 2l, is arranged in the passage 19 and projects below the body 5 to engage the head 13. A stop or stops 2A may be provided to limit the upward movement of the head.

In practice the springs 15 hold the liquidvalve normally seated to close the iilling-tube, and when a'bottle is arranged in position on the filling-tube with its mouth against the seat 14 and moved by. any suitable means to force the head upward against the tension of the springs 15 the liquid-valve is moved with the head and unseated. At the initial upward movement of the head the stem is caused to unseat the air-valve, so that the pressure in the bottle will be equalized with that in the tank before the liquid-valve is completely opened by the continued upward movement of the head. In this way I prevent the beer from being forced into the bottle underthe pressure in the tank by providing' the same pressure in the bottle, so that the beer will flow into the bottle by gravity without producing foam.

My improved valve mechanism is very simple in construction and can be easily connected with a supply-tank or other source of supply. It is susceptible ot' many changes in the form and proportion of parts and details of construction without departing from its scope, and therefore I do not restrict the invention to the particular embodiment herein disclosed.

Without limiting myself to the exact construction and arrangement of parts herein shown and described, what I claim, and desire to secure by Letters Patent, is

l. A lilling-valve mechanism for bottle-lilling machines comprising a body provided with a liquid-passage, a filling-tube connected with said passage, a liquid-valve, a head slidable on the illing-tube and connected with said liquid-valve, ,an air-passage in the body at one side of the liquid-passage, an air-valve in said passage, and a stem in the air-passage adapted to be engaged and moved by the head to unseat said aix-valve 2. A lilling-valve mechanism for bottle-lill ing machines comprising a bodyY provided with a liquid-passage, a l'illing-tube connected with said passage, a li p1idvalve, ahead movable on the filling-tube and connected to said liquid-valve7 an inclosed chamber between the body and thehead, an air-passage in the body opening at the bottom thereofI Within said chamber, an ai1-valve in said passage, and a stem in said passage adapted to be moved by the head to unseat the air-valve.

3. A lilling-valve mechanism for bottle-lilling machines comprising a body provided with a liquid-passage, a filling-tube connected with said passage, a liquid-valve, a head having an enlarged bore and movable on said filling-tube and connected with said liquid-valve, a gasket seated in the opposing faces of the body and head and inclosing an air-chamber around the lilling-tube, an air-passage in the body opening at the bottom thereol'l in said air-chamber, an air-valve in said passage, a stem in the passage projecting below the body to engage the head and adapted to be moved by the head to unseat the air-valve, and a pipe connected to said air-passage and opening into the liquid-supply tank above the level of the liquid therein.
